UNIVERSAL FRICTIONAL HINGE.

SPECIFICATION forming part of Letters Patent No. 763,220, dated June 21,1904.

Application filed April 19, 1904.

To all whom it may concern:

Be it known that I, FRANCIs E. TOTTEN, a citizen of the United States,residing at N ewark, in the county of Essex and State of New Jersey,have invented certain new and useful Im provements in UniversalFrictional Hinges; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to numeralsofreference marked thereon, which form a part of this specification.

The objects of this invention are to secure a positive movement of partsin frictional relation in adjustable fixturessuch as mirrors, towelracks or bars, adjustable shelves, robehooks, brackets, and similararticles adapted to be secured upon the wall of a room or other fixture;to enable the desired adjustments of parts in frictional contact to bemaintained with greater certainty and with such a friction as will holdthe movable parts positively in position after adjustment; to avoid alluse of set-screws or other hand-operable fixing devices such as willtend to impair the appearance of the device and render it moreexpensive, and to secure other advantages and results, some of which maybe referred to hereinafter in connection with the description of theworking parts.

The invention consists in the improved adjustable bracket or support formirrors or other articles and in the arrangements and combinations ofparts of the same, all substantially as will be hereinafter set forth,and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like numerals ofreference indicate cor- .responding parts in each of the severalfigures,

. tion of the parts to any desired extent. said inner friction-tube 7 ispreferably split,

Serial No. 203,842. (No model.)

has at its front two tubes or hollow cylinders 6 6, rigidly fixedthereon in axial alinement, but a little apart from one another, thesaid cylinders having therein a friction-tube 7, which extends from onefixed tube to the other, as shown in Fig. 2. Said friction-tube is atits opposite ends provided interiorly with threads 8, adapted to receivetapering or conical screws 10. Into the opposite ends of thefriction-tube 7 are inserted the said conical screws 10, and when thelatter are turned inward the ends of the friction-tube are forced intofrictional contact with their respective outer cylinders 6, the screwsexpanding the saidends of the tube and increasing the fric- The as at11, only part way'through its length and is rigidly fastened to theprojecting head 12 of the bracket. The said projecting head ishorizontally bored and through the boring is inserted the tube 7, thesame being fastened intermediate of its split ends to said head by meansof the pin or screw 13, which latter is inserted in the head andfriction-tube provided with female threads for the purpose. Thus theheadand friction-tube work together and the friction-tube cannot movelongitudinally except when the screw 13 is removed.

The forward end of the head 12, which is enlarged for the purpose, isvertically perforated, as at 1 1, to receive a friction-piece 15, whichis split where it enters said head and is soldered or otherwise securedwithin the arm 16, to which a mirror-plate 17 or a shelf or otherarticle or device is held in frictional contact. Said friction-piece 15is fitted within the tubular arm 16 and soldered or similarly securedtherein, and the split portion 18 is somewhat enlarged, so as to form ashoulder 19 to receive the end of the tube; but said end of the tubeprojects beyond said shoulder 19 to form a second shoulder 20 to engagethe head 12. The arm 16 is thus in pivotal relation to the head, so asturn horizontally therein, and its pivotal movements are made easy orless easy by turning the conical screw 21 within the said threadedfriction-piece. The

mirror-plate 17 is also provided with a head 24, vertically perforatedto receive the vertical free extremity of the arm 16, which arm ispreferably S shape, the said arm being provided at said free extremitywith another split friction-piece 25 and conical screw 26 similar tothose already described.

the construction described the mirror or the plate 17 can be turnedvertically or horizontally, and the horizontal movements can be eitheron the center 25 or on the center 15. Should there be any unduelooseness because of wear, such looseness can be readily taken up bymeans of the screws 10, 22, or 26.

I am aware that various modifications of construction may be employedwithout departing from the spirit or scope of the invention, and I donot wish to be understood as limiting my self by the various descriptiveterms hereinbefore employed, excepting as the state of the art mayrequire. 7

Having thus described the invention, what I claim as new is- 1. Theimproved bracket or adjustable fixture herein described, the joints ofwhich are provided with split friction-tubes in which are insertedconical screws adapted to expand the said friction-tubes to increase thefriction, substantially as set forth.

2. The combination with a plate having two hollow cylinders fixedthereto in alinement, said cylinders being arranged apart, and having aprojecting perforated head between, a friction-tube extending throughsaid head and into said cylinders and conical screws extendingoppositely into the opposite ends of said friction-piece, said headbeing perforated vertically at its projecting end, an arm having a splitfriction-piece lying in the vertical perforation and a conical screwholding it therein, and a plate pivoted at the free end of said arm,substantially as set forth.

3. The combination, in abracket, of a plate having two hollow cylindersin alinement with a space between, a friction-tube split at oppositeends and at its split ends lying in said hollow cylinders, and a headarranged between said cylinders on said arm, a screw holding saidfriction-tube in fixed relation to said head, said head serving as asupport for an arm or other attachment, substantially as set forth.

4. The combination, in a bracket, of a plate having two hollow cylindersin'alinement with a space between, a friction-tube split at oppositeends and at its split ends lying in said cylinders, and a head arrangedbetween said cylinders on said arm, a screw extending through the headinto the friction-tube, the plate between said cylinders being open topermit the insertion and removal of said screw, said screw holding saidfriction-tube in fixed relation to said head, and said head serving as asupport for an arm or other attachment, substantially as set forth.

In testimony that 1 claim the foregoing I have hereunto set my hand this8th day of April, 1904:.

FRANCIS E. TOTTEN.
